A radiation detector includes a first pixel and a second pixel disposed in a same column, a first comparator connected with the first pixel via a first vertical signal line, and a second comparator connected with the second pixel via a second vertical signal line. A first distance from a conversion portion of the first pixel to the first vertical signal line is different from a second distance from a conversion portion of the second pixel to the second vertical signal line. The first comparator is configured to receive a first reference signal and compare the first reference signal with an output signal sent from the first pixel. The second comparator is configured to receive a second reference signal and compare the second reference signal with an output signal sent from the second pixel. The second reference signal is different from the first reference signal.
